Game crashes when a custom block spawns loot (from an event) when broken

I've been experimenting with the new block components today. One of them being the "minecraft:on_player_destroyed" component. When said block is destroyed, an event plays that triggers a randomizer (Randomizer A in this case to prevent confusion), which picks a few options. When Randomizer A picks the third option (it is set to 100 weight so it is more likely), which is another randomizer (Randomizer B), it picks one of four options, each which "spawn_loot". I used the sheep, chicken, pig, and cow loot table in this case. When in game, destroying the block causes the game to crash half of the time.

Steps to Reproduce:
1. Make an add-on with a custom block with the following code (this is my code):
{
"format_version": "1.16.100",
"minecraft:block": {
"description": {
"identifier": "wacky:wacky_block"
},
"components": {
"minecraft:display_name": "wacky:wacky_block",
"minecraft:unit_cube": {},
"minecraft:destroy_time": 0.85,
"minecraft:on_player_destroyed": {
"event": "lucky_block_break"
}
},
"events": {
"lucky_block_break": {
"randomize": [
{
"run_command": {
"command": [
"setblock ~ ~ ~ diamond_block"
]
}
},
{
"run_command": {
"command": [
"give @p stick 1"
]
}
},
{
"run_command": {
"command": [
"clone ~ ~-10 ~ ~5 ~5 ~5 ~ ~20 ~"
]
}
},
{
"randomize": [
{
"spawn_loot": {
"table": "loot_tables/entities/cow.json"
}
},
{
"spawn_loot": {
"table": "loot_tables/entities/pig.json"
}
},
{
"spawn_loot": {
"table": "loot_tables/entities/sheep.json"
}
},
{
"spawn_loot": {
"table": "loot_tables/entities/chicken.json"
}
}
],
"weight": 100
},
{
"run_command": {
"command": [
"summon slime ~ ~2 ~"
]
}
},
{
"run_command": {
"command": [
"execute @p ~ ~ ~ structure load obsidian_trap ~-1 ~ ~-1"
]
}
},
{
"run_command": {
"command": [
"execute @p ~ ~ ~ structure load lava_pit ~-3 ~-50 ~-3"
]
}
}
]
}
}
}
}
2. Destroy the custom block.

Expected Results:
The custom block drops either a cow's, sheep's, pig's, or chicken's death loot table.

Observed Results:
The game crashes. I have tested this three times.

On a side note, the options listed in Randomizer A work perfectly fine (apart from the third one, of course.)
